STEM WINDING AND SETTING FOR WATCHES.

Application filed April 14, 1917.

To all whom it may concern:

Be it known that I, ALBERT ALEXANDRE, a citizen of the Republic of Switzerland, residing at Fresno, in the county of Fresno and State of California, have invented a new and useful Stem Winding and Setting Means for atches, of which the following is a specification.

This invention has reference to stem winding and setting means for watches, and its spring is under the control of the winding stem of the watch and the shipper engages the shifting clutch of the watch, said stem and clutch being of the ordinary character common in stem winding watches- The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings Figure 1 is a face view of a watch with the invention applied, but omitting many parts of the watch unnecessary for an understanding of the invention. v

F ig. 2 is a view similar to Fig. 1 but showing the winding and setting mechanism in a different position from that of Fig. 1.

Fig. 3 is a perspective view of the pendent lever spring or shipper lever enlarged.

Fig. 4c is a perspective view of the clutch lever spring or shipper enlarged.

Fig. 5 shows a guard or keeper for holding certain parts against displacement, and also enlarged.

Referring to the drawings there is shown Specification of Letters Patent.

a winding and setting arbor 1 passing through a winding pinion 2,'which latter is provided with ratchet teeth 3 surrounding the arbor 1. Mounted to slide'on and turn with the arbor is a shifting clutch 4 having teeth 5 to engage the teeth 3, so that when the knob 6 is turnedin the usual manner, the shifting clutch is rotated and with it the winding pinion 2.

The winding arbor 1 has a rounded extension 7 terminating in a head 8 and passing through and capable of longitudinal movement in a bearing 9. That end of the shifting clutch remote from the winding pinion is formed with teeth 10 for engaging a setting pinion, indicated in dotted lines at 11. The shifting clutch is provided with an intermediately located circumferential groove 12.

The parts so far. described may correspond in the main with similar parts in the winding and setting mechanism of watches as ordinarily constructed.

Mounted on anappropriate one of the plates ofthe watch is a shipper 13 shown separately in Fig. 4:. This shipper comprises a-hub portion 14: held in placeby a pivot screw 15 and capable of rocking thereon. The hub 14 carries two divergent arms 16, 17 which may be considered as spring arms, the arm 16 terminating in a head 18 fast thereon and of a size to engage snugly, yet freely, in the groove 12.

Mounted adjacent to the shipper 13 is a lever 19 having a hub portion 20 pivoted to a fixed part of the watch movement by a pivot screw 20. The lever 19 has divergent arms 21', 22 fast to and extending therefrom, the outer end of the arm 22 being provided "with a continuation 23 extending about but spaced from the hub 20, and then bent to pass the free end of the arm 21, the extension 23 being a springextension and having a tendency toward the arm 21, so as to engage the latter when free to do so. The endof the arm 22 joined to the extension 23 is located in the path of the head 8 of the winding arbor 1 to be rocked thereby in one direction, while spring means incorporated in the shipper 18 and lever 19 tends to move the lever 19 in the opposite direction.'

A keeper or guard 24: is so placed as to prevent displacement of the head 18 from the groove 12in the operation of the demos.

The spring arms 16 and .17 may be-normally straight and the extension 23 and arm 21 may be normally in contact, this being before the parts are in the assembled position. The spring arm 17 is introduced between the arm 21 and extension 23 where opposite the arm 21, and the extension 23 where engaging the spring arm 17 is somewhat curved. The extension 23 is also somewhat elastic, so that the spring arm 17 at its free end where introduced between the head 6 is in the pushed in condition the head 8 on the end of the winding arbor is also pushed in toward the central portion of the watch, this resulting in rocking the shipper lever 19, so that the free end of the extension 23 pushes against the free end of the arm 17, puttingthe latter under more or-less spring tension and causing a rocking of the shipper on its pivot 15 in a direction to actuate the shifting clutch by means of the'arm 16 and head 18 toward the pinion 2 until the clutch teeth 3 and 5 engage. Now, the winding operation may be performed at any time.

If, however, it is desired to set the watch the head or knob 6 is drawn out, this causing an approach of the head 8 to the bearing 9, whereupon pressure upon the arm 22 of the lever 19 is released, and the tendency of the spring arm 17 and the spring extension 23 to return to their normal condition causes the arm 22 to follow the head 8 and consequently causes a rocking of the shipper in a direction to actuate the shifting clutch through the arm 16 and head 18toward'the setting pinion 11/ This results in bringing the teeth 10 of the shifting clutch into engagement with the setting pinion, wherebers in relatively yieldable relation and between the ends of which is inserted and elastically gripped the end of that arm of the shipper remote from the arm engaging the clutch.

2. In a watch, means for transmitting motion from the winding and setting arbor of the watch to the shifting clutch, comprising two substantially V-shaped levers each pivoted at the angle portion, one lever constituting a shipper and having two spring arms, one of which engages the clutch, and the other lever constituting a shipper lever and having one of its arms formed of two members in yieldable relation, which members normally meet near their ends and elastically grip the end of the other spring arm of the shipper, the second arm of the shipper lever engaging the winding and setting arbor of the watch.

3. In a watch, means for transmitting motion from the winding and setting arbor of the watch to the shifting clutch, comprising two rock levers each having interconnected though readily separable spring arms, and other arms, one of which is a spring arm and engages the clutch and the other engages the said arbor.

4. In a watch, means for transmitting motion from the winding and setting arbor of the watch t the shifting clutch, comprising a rockable shipper with two divergent spring arms, one of which engages the shifting clutch, and a rockable shipper lever having divergent arms, one engaging the end of :the winding and setting arbor, said arm having a resilient extension prolonged into operative relation to-the other arm of the said lever, said extension and second-named arm meeting at an angle to each other and receiving between them and elastically gripping the end of the second spring arm of thership'per in all positions of the shipper and its leverl In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
